CARPET-CLEANING MACHINE.

SPECIFICATION forming part of Letters Patent No. 739,611, dated. September 22, 1903.

7 Application filed March 23, 1903. enial No. 149,085. (No model.)

To all 1; 7mm, it may concern:

Be it known that I, JosEP LEwANnoWFsKI, a citizen of the United States of America, re-

siding at Allegheny, in the county of Alle gheny and State of Pennsylvania, have invented certain new and useful Improvements in Carpet-Cleaning Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in carpet-cleaning machines; and the object of the invention isto provide a simple; cheap, and effective machine adapted either for household use or for carpet-cleaning establishments, though particularly adapted as a small machine for household use.

Another object of the invention is to construct a machine of this type which when not in use may be folded in such a manner as to occupy but comparatively little space; to provide means for supporting the carpet in such position that it may be readily drawn underneath the heaters to be engaged thereby; to provide a series of heaters to clean the carpet as it is drawn underneath the heaters; means for operating said heaters; means for holding the heaters normally inoperative when desired, and other features of construction, as will be hereinaftermore specifically described and then particularly pointed out in the appendedclaims I In describing the invention in detail reference will be had to the accompanying drawings, forming a part ofthis application, and wherein like numerals of referencewill be employed for indicating like parts throughout the differentviews of the drawings, in which- Figure 1 is a detail top plan view of my improved carpet-beating machine in the eX-.

tended position. Fig. 2 is a side elevation of the same. Fig. 3 is a cross-sectional view taken on the line 33 'of Fig. 1 looking in the directionof the arrow. Fig. {i is a like view taken on the'line 4 i of Fig. 1 looking in the direction of the arrow. Fig. 5 is 'a'detail side elevation of the machine in the'folded form.

To put my invention into practice, I provide a pair of standards or housings 1, mounted on pedestals or bases 2, in one end of which are placed rollers 3, the other ends of the pedestals or bases being adapted to engage directly with the floor. The pedestal or base of each standard is connected to the other by a cross-brace 4, and at the upper ends of the standards or housings they are connected by a brace 5. The standards or housings are provided on their forwardedge or face with bearings 6, in which is j ournaled the beater-actuating shaft '7, provided with cams or knockers 8, staggered on the shaft, there being two cams or knockers for eachbeater, whereby each beater is actuated twice with one revolution of the shaft 7. For a small machine adapted for household use the shaft may be driven by means of a crank 9 on one end thereof, and if a large machine is to be built for factory purposes a belt-pulley may be substituted for the crank, whereby the shaft mayby operated by steam or other power. The standards or housings are also provided on their rear edges or faces with bearings 10, in which is j ournaled a shaft 1 1, which carries the heaters. These heaters are each made in two sections or members, the section or member 12 being mounted on the shaft 11 and the section or memberld being detachably secured to the section or member 12. This is preferable in order that if one of the boaters be broken a new one may readily be placed in position without requiring the necessity ofdisconnecting the member or section 12 of the' beater from the shaft 11. A convenient method of securing, the sections or members together is by providing a headed stud or pin 16 on the'sections or members l2 and providing the ends of the sections or members 14 with a notch 17 to receive said headed stud, pin, or screw 16. A bolt 18 is passed through the two sections near the ends of the sections 12 and preferably secured by a winged nut 19, as shown.

The heaters are pulled down by the action of springs 20, connected at their upper ends to the sections or members 12 of the boaters and at their lower ends connected to a tensionregulating bar 21, pivoted or hinged at its one end to the standard or housing base, the op posite end of this bar being under the tension of a spring 22. This spring 22 is arranged on a bolt 23, carried by the pedestal orbase 2, and provided on its upper end with a winged nut 24, which when turned down forces the bar 21 downwardly, compressing spring 22 and increasing the tension of springs 20. The beaters may be held in the normally elevated position whereby to permit the insertion of the carpet into position or the removal of the same by means of a presser-bar 25, carried on a rod or stem 26, which extends through the top cross-bar 5 and is pivotally connected to a lever 2.7, pivoted at 28 to said top cross-bar 5. This lever carries a hook 29, adapted to be engaged with an eye 30, carried by one of the standards or housings for holding the presser-ba'r depressed in engagement with the beaters and the latter elevated. This presserbar is held normally elevated by means of a spring 31,arranged on the stem 16,between the cross-bar 5 and a shoulder 32 on said stem, the stem being connected to the lever by means of a small link The carpet to be cleaned is supported in position for engagement by the beaters on a foldable frame, so connected to the standards or housings as to be moved into horizontal position for use and when not in use to b folded up against the housings or standards. To this end each side rail of the frame is constructed in two sections or members 34 35, hinged together, as at 36, and when in the extended alined position, as shown in 1 and 2, held by means of clips 37, carried by the sections or members 34. These clips or keepers are provided with slots 38 to receive headed studs or pins 39, on which the keepers or clips slide, the said clips or keepers spanning the joint when therails are alined.

The sections or members 34 of the side rails are provided with slots 40, which receive bolts 41, carried by the standards" or housings and have winged nuts 42, adapted to impinge againstthe outer face of the sec-' tions 34 and hold the rails in the position to which they have been adjusted. Means is provided at each side of the frame for sup porting the carpet to be cleaned. To this end I secure to each of the sections 35 of the side rails a foldable supporting frame embodying transversely-extending bars 43, pivoted at their inner ends to the sections or members 35 of the side rails, and at their outer ends pivotally connected to a bar 44. To the central one of the bars 43 is attached pivotally, in order that it may fold, a supby the beaters on a flexible bed, preferably across from one side rail to the other.

composed of a series of cords 49, stretched For this bed I have found cords to be the more preferable, as in event of the beaters striking the same it is not liable to break the beaters,

and they are flexible enough to give under the stroke of the beaters. The side rails of the frame are supported near their outer ends by means of supporting legs 50, pivotally attached to the members or sections 35 of the rails. In order to drive all dust and foreign matter away from the carpet as it is extracted and toward the rear of the frame, I provide a fan 51, journaled in bearings 52, suspended from the underneath face of the sections or members 35, a pulley 53 being mounted on the shaft of this fan and connected by cord or belt 54 with a pulley 55 on the beater-actuating shaft 7.

In operation the frame is extended and the supporting-frames swung out to the supporting position to receive the carpet. The carpet is placed in a roll on one of the supporting-frames and drawn across the supportingbed. For convenience in drawing the carpet across the supporting-bed the beaters may be held elevated, which is readily accomplished by depressing lever 27, so as to force presserbar 25 into engagement with the sections or members 12, depressing the front ends of said beaters and elevating their outer ends, the lever being held by engaging hook 29 in eye 30. WVhen the carpet has been positioned, the presserbar is then released and rotary motion imparted to shaft 7. This causes the cams or knockers to engage the upper faces of the sections or members 12 of the beaters near their forward ends and elevate the outer ends of the beaters. As the cams or knockers pass out of engagement with the sections or members 12 of the beaters the latter are drawn down rapidly under the action of the springs 20 andstrikethe carpetwith considerableforce to drive out the dust and other foreign substance. The cams or knockers are so placed on the shaft as to alternately engage with the beaters, and two cams or knockers are provided for each beater, whereby the latter will be given two strokes with each revolution by the shaft. The dust as it is beat out of the carpet is expelled toward the rear of the frame of the fan, thus preventing the same from settling again in the carpet or inconveniencing the operator. The carpet as it is drawn across the rollers 48 and bed 49 is supported on the opposite supporting-frame and is therefore not subjected to any of the dust driven down through the carpet by the beaters. In the present illustration I have shown but three beaters; but of course this number may be increased, if desired.

When the machine is not in use it may be folded in a comparatively compact form by simply slackening up nuts 42, folding up the carpet-supporting frames at the sides of the side rails, and sliding back clips 37 past the joint between sections 34 and 35, whereby said sections may be folded in the manner shown in Fig. 5. The supporting-legs 50 fold up against the sections or members 35 of the side rails, and as the bars 43 are pivotally connected to the sections 35 they may be folded against the same when hooks 46 are detached, while each of the legs 45 being pivoted to one of the bars 43 this leg can be folded up with the folding of bars 43 and bars 44.

While I have herein shown and described the invention in detail as it is practiced by me, yet it will he observed that in the construction of the machine various changes may be made in the details of construction without departing from the general spirit of my a shaft journaled in the housings or standards, an actuating shaft journaled in said housings or standards, cams or knockers carried bysaid shaft for engagement with the heaters for vibrating the same, and means for operating said actuatingshaft, substantially as described.

2. The combination with a plurality of pivoted heaters, and means for operating the said beaters, and means for forcing the said heaters down to engagement with the carpet, said means comprising a regulating-bar pivoted at one end, springs connected to said bar and heaters respectively, and means connected to the unpivoted end of said bar for adjusting the same.

3. In combination with the heaters and means for supporting the same, means for elevating the said heaters, a pressure-bar, a rod connected to said bar and being mounted in a supporting means, a lever pivoted to said rod and to the supporting means, means for holding said lever in a lowered position, and means for elevating said lever when it is'released.

In testimony whereof I affiX my signature in the presence of two witnesses.

JOSEP LEWANDOWFSKI.
